Tusk Muses About France’s Force De Frappe 03/21/2025

Tusk Muses About France’s Force De Frappe Donald Tusk — not the indulgent follow up to the perfect Fleetwood Mac Album Rumours — mused recently about the future of deterrence in Europe. The discussion reminds of the challenges of extended deterrence, the oh so very French debate about nuclear weapons and European security, and the vibe shift that has raised questions about the future US security guarantee. Links of Note: Building a Euro Deterrent: Easier Said Than Done, by Pranay Vaddi and Vipin Narang https://open.substack.com/pub/strategicsimplicity/p/building-a-euro-deterrent-easier?r=1l9z0c&utm_medium=ios Support us over at ! /episode/index/show/armscontrolwonk/id/35800730

The Oreshnik IRBM 11/23/2024

The Oreshnik IRBM Russia launched an experimental, offensive missile into Ukraine, aimed at the PA Pivdenmash (former Yuzhmash) factory. This is a new world of missile combat, as this looks to be the first use of an IRBM (though not at IRBM ranges) and possibly MIRV (though conventional!) in combat. Jeffrey and Aaron talk about Russia's new Oreshnik missile, what it is, its relationship to the RS-26 Rubezh IRBM/ICBM/treaty-skirting missile, the Typhon-Oreshnik European strike dyad, and the looming new Euromissile crisis.

The Big Honking Hyunmoo-V 10/20/2024

The Big Honking Hyunmoo-V An absolutely massive mobile ballistic missile was paraded in North.... ...wait sorry.... South Korea. Force of habit. Decker joins Jeffrey to talk about the absolute unit that the ROK just showed off. But don't worry, it's just an "SRBM with an eight ton warhead," nothing to see here. The team talks about messaging, move/countermoves on the Korean Peninsula, and who actually started this dang missile race to begin with. Audio Originally Recorded October 2nd.

A Chinese ICBM Test in the Pacific 10/20/2024

A Chinese ICBM Test in the Pacific China tested an ICBM deep into the Pacific Ocean, instead of short-shooting it into PRC deserts. Decker Eveleth joins Jeffrey to talk about why this is a fascinating change in behavior for the PLA Rocket Force and PRC in general. China has only ever done this twice before, both over 40 years ago, back in 1980. Decker and Jeffrey talk about the internally signalling mechanisms, the issues with corruption in the PLARF, China's potential move to US and Russian style ICBM test notifications, strategic stability, and our favorite: absolutely gorgeous high-resolution photos of solid-fuel ICBMs. Audio Originally Recorded September 27th Support us over at ! /episode/index/show/armscontrolwonk/id/33534967

Iran's October Missile Raid 10/03/2024

Iran's October Missile Raid Iran just launched what may be the largest single missile raid in history, and Israel claims no Israeli deaths. While we're still very early in the news cycle, Jeffrey and Aaron start picking apart the information available to look at what we can learn about the state of the Iranian offensive missile arsenal, weight what Iran's options for next steps are, and dive into the internal nuclear politics of both Israel and Iran.

Busting the Burevestnik 09/18/2024

Busting the Burevestnik Friend of the Pod Decker Eveleth found the Burevestnik deployment site, it seems! Decker, of the CNA Corporation, has tracked down what appears to be aka the SSC-X-9 Skyfall, using Planet Labs satellite imagery. It appears to be about 300 miles north of Mosco, near a national-level nuclear storage facility. Decker and Jeffrey talk through Decker's methodology for identifying the storage facility, why Russia may deploy such a dangerous system so close to major cities, and the bureaucratic politics that could be driving the development of this bizarre weapon.

TYPHON, FATHER OF MONSTERS 06/24/2024

TYPHON, FATHER OF MONSTERS Jeffrey and his team have been OSINT'ing the heck out of the deployment of the Typhon Strategic Mid-Range Fires (SMRF) ((Typhon Smurf?)) to the Philippines, and tracked down the airport and deployment zone. Recently the U.S. Army deployed the new Typhon SMRF system to the Philippines as part of an exercise, raising the ire of both the Russian and Chinese governments. The Army seemed to try and keep it relatively low profile initially but the Philippines just....tweeted it out basically. As the Pacific continues to bristle with missiles, Jeffrey and Aaron talk about regional escalation dynamics, who is buying what missiles, and who they are (or aren't?) actually pointed at...

Russian Entanglement 06/24/2024

Russian Entanglement Tom Schelling described escalation as a "curved slope" where you won't be able to predict when the final drop occurs, and Ukraine targeting an early warning radar in Russia certainly is at least a few steps down that slop. Jeffrey and Aaron sit down at the intersection of "legitimate conventional military target" and "direct cause of nuclear escalation" to talk about the risks and justifications for bringing EW systems into a conflict, and discuss James Acton's idea of modern entanglement, and the connection between modern conventional and nuclear operations.

Iran and Israel's Missile War 05/18/2024

Iran and Israel's Missile War We have data! Jeffrey and Aaron walk through the new primary source data to figure out if either Iran's missile raid or Israeli's missile defense efforts were effective. This appears to be the first time that successful wartime ballistic missile defense intercepts can be validated via open source means, which is a major step forward for open source missile and BMD analysis. Jeffrey and Aaron also talk about the relative impact of conventional ballistic missiles, and what secondary effects must be considered when assessing the value of interceptors vs. offensive missiles. This one gets wonky. Support us over at ! /episode/index/show/armscontrolwonk/id/31366057

Iran's Once in a Lifetime Moment 04/17/2024

Iran's Once in a Lifetime Moment not complying with the IAEA And you may find yourself in a war in another part of the world And you may find yourself making a metaphor about an automobile And you may find yourself enriching your uranium stocks, and building reactors And you may ask yourself "Well, how did I get here?" Letting the days go by, politics will hold you down Letting the days go by, heavy water underground Into Fordow again, maybe to Isfahan Once in a lifetime, realignment all around Same as it ever was, Same as it ever was Jeffrey and Aaron go through the current state of play in Iranian politics (just prior to its massive missile strike on Israel), particularly around the nuclear program and what the bomb genuinely means for security and Iranian internal politics, and review how we got here over the past 20 years of Arms Control Wonkery.

Russian Nuclear Doctrine in the Financial Times 2: A Conversation with William Alberque 04/10/2024

Russian Nuclear Doctrine in the Financial Times 2: A Conversation with William Alberque William joins Jeffrey for a friendly and deep debate about the Russian Navy nuclear documents leaked to FT, covered in our . This is a fascinating discussion not only on the documents themselves, but what they imply for Russia's view of its own territorial integrity, what it needs to convince its soldiers to go to bat for, and the eternal issues of "self-deterrence".

Russian Nuclear Doctrine in the Financial Times 03/10/2024

Russian Nuclear Doctrine in the Financial Times Max Seddon and Chris Cook with the Financial Times have on leaked Russian Naval documents that FT saw, focused on thresholds for Russian nuclear use, especially in a war scenario with China. Jeffrey and Aaron go through what the documents reveal and debate if they're generally consistant with what is understood about Russian nuclear doctrine or, as FT states, indicate that the threshold is lower than previous understood.

Jeffrey Visits the Test Site 02/19/2024

Jeffrey Visits the Test Site Road trip to Vegas. As part of an NGO transparency visit, NNSA opened up the Nevada Test Site to a group of international nuclear weapons experts, including one Dr. Jeffrey Lewis. Jeffrey goes through what he saw: P Tunnel, The BEEF, and the crown jewel, U1a. This was an NNSA exercise in transparency, aimed at showing the community and world that the U.S. stockpile stewardship and treaty verification exercises are separate from nuclear explosive tests. It was also, and we cannot underline this enough, extremely cool. Support us over at ! /episode/index/show/armscontrolwonk/id/30016133

Russia Buys North Korean Missiles 01/17/2024

Russia Buys North Korean Missiles Shoigu went shopping. Russia is buying KN-23 and KN-25 missiles from North Korea and launching them in support of its invasion of Ukraine. Imagery from on the ground clearly shows North Korean style solid-propellant missiles. Jeffrey and Aaron talk about what this means for global ballistic missile proliferation, possible South Korean responses, and the continued rise of North Korea as a ballistic missile exporter.

North Korea's New Satellite 11/28/2023

North Korea's New Satellite North Korea finally got a reconnaissance satellite into orbit, after several failed prior attempts! While it is a little rough around the edges, every program has to start somewhere. Jeffrey and Aaron talk through the implications of the DPRK's reconnaissance satellite, the relationship of the DPRK missile and space programs, and the importance of high fashion for the spacelaunching elites.

The Reason We're all Still Here 10/14/2023

The Reason We're all Still Here Take a listen to the latest season of Jeffrey Lewis's podcast, Far too often, governments behave like toddlers. They’re fickle. They don’t like to share. And good luck getting them to pay attention to any problem that isn’t directly in front of them. They like to push each other to the brink, and often do. But when they don’t, it’s usually because other people enter the proverbial room. Private citizens who step up and play peacemaker when their governments won’t or can’t. People who strive for collaboration and understanding, and sometimes end up finding it in unlikely places. Those people and the work they do, they’re the reason we’re all still here. This season, we’ll hear from scientists, analysts, and idealists who have gone to crazy lengths just for a shot at making peace and building understanding From smoke-filled rooms in North Korea to secret labs in the Soviet Union… to the lawless seas, and even to the depths of outer space (or, at least, the conference rooms where they talk about the depths of outer space). This podcast tells the stories about the people holding us back from the brink. Hosted by Dr. Jeffrey Lewis, a professor and scholar at the Middlebury Institute of International Studies on the Nonproliferation and Terrorism Studies faculty. Previously, he served as Director of the Nuclear Strategy and Nonproliferation Initiative at the New America Foundation and Executive Director of the Managing the Atom Project at the Belfer Center for Science and International Affairs at Harvard University. He is the founder of ArmsControlWonk.com, a leading resource on disarmament, arms control and nonproliferation issues.

Shenanigans in Novaya Zemlya 10/11/2023

Shenanigans in Novaya Zemlya Looks like everyone is preparing for a party. Between Russia's potential un-signing of a nuclear test treaty, threats to test "if the United States does," and refurbishments at Novaya Zemlya, things aren't looking great for the longevity of nuclear test ban norms. China and the U.S. have been modernizing too, though the U.S. has offered to allow monitors on-site to verify U.S. lack of testing. Jeffrey and Aaron sit down to talk about the recent developments in Russia, and the likelyhood that there will be a return to explosive nuclear testing in the future. The Era Without Arms Control continues, and threatens to deepen. Support us over at ! /episode/index/show/armscontrolwonk/id/28293824

Kim Jong Un's Excellent Adventure 08/17/2023

Kim Jong Un's Excellent Adventure Sam Lair joins the podcast to talk about Kim Jong Un's recent whirlwind tour of the North Korean Defense Industrial Base with Jeffrey and Scott. If you're into missiles, geolocation, and machine tools (and, if you listen to this podcast, you probably are), you're going to want to tune in. Sam and Jeffrey have been mapping out the DPRK DIB, including plant managers, machine tool lineages, production lines, and evolutions over time. Kim's visit to these plants, and the accompanying KCNA imagery storm, unlocked a trove of new information about where nuclear delivery systems are produced and maintained, and updated our ideas for how big the arsenal may be.

Oppenheimer 08/07/2023

Oppenheimer Jeffrey is joined by the illustrious Kelsey Atherton to discuss Christopher Nolan's film Oppenheimer, as well as the history and legacy of the titular man himself. Kelsey and Jeffrey dive into the choice to focus on Oppenheimer's own security legacy and bypass the direct and indirect horrors affected upon the Congolese miners, New Mexicans, and Japanese civilians, as well as the intentional rendering of power politics and personal animus within the U.S. security apparatus. Kelsey penned a , talking about the wider related experience of watching Barbie and Oppenheimer in the same day. Support us over at ! /episode/index/show/armscontrolwonk/id/27686544

Hiroshima 2023 08/05/2023

Hiroshima 2023 Jeffrey is back from Hiroshima, where he participated in a Track 2 nuclear dialogue. The outlook for near-term arms control is still grim. Jeffrey and Aaron unpack the G7 statements on disarmament that the Japanese representatives wanted to re-affirm, the tacit condemnation of Russian and Chinese contained within, and the global theater around narrative control of arms control. Russian, US, and third party interpretations of CTBT and disarmament discussions create significant friction, but the discussion is well moderated by the traditional 5:00 happy hour.

What the F*** Do They Think the Russians are Going to Shoot at Them?! 07/18/2023

What the F*** Do They Think the Russians are Going to Shoot at Them?! Germany has a gap that needs to be filled in the face of Russian threats. But this time it isn't Fulda, it is....the exoatmospheric layer of ballistic missile defenses? Jeffrey and Aaron try to understand Germany's decision to buy the very fancy Israeli/American Arrow-3 exoatmospheric BMD system, in absense of a specific Russian missile system and despite two Aegis Ashore sites coming online in Europe.

Failure to Launch 07/06/2023

Failure to Launch Jeffrey is back from Japan and North Korea's satellite-turned-submarine is back from the bottom of the ocean! North Korea's failed Chollima-1 space launcher and its payload, the Malligyong-1, failed to reach space on May 30. Jeffrey and Aaron talk about the Japanese response to the launch, the North Korean reponse to the failure, and whether or not people are tacitly starting to accept North Korean space capabilities. Are the DPRK's space capabilities overlapping with their missile capabilities? How far have their technological arcs diverged, and where are they still overlapping? And is the Chollima-1's second stage a stolen Ukrainian design, or something new and domestic? Support us over at ! /episode/index/show/armscontrolwonk/id/27393705
